DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door mirror with a heater for an automobile.

[0002]

2. Description of the Related Art As a conventional door mirror with a heater of this type, for example, a mirror as shown in FIGS. 6 and 7 is known (introduction of a new model N15 type vehicle issued by Nissan Motor Co., Ltd.). "reference).

In FIG. 6, reference numeral 1 denotes an electric storage motor as a storage drive actuator for deploying and storing a door mirror provided on the side of the vehicle. The electric storage motor 1 is provided in a resin housing of the door mirror. It is connected to the stored mirror control circuit 2.

The in-mirror control circuit 2 is configured to be connected to a vehicle body-side power supply 4 via an electronic mirror control switch section 3 disposed inside the vehicle compartment.

[0005] Among these, the control circuit 2 in the mirror, when turning the seesaw switch 5 of the electrical mirror control switch unit 3 forward or reverse as shown in FIG.
The internal relay 6 is turned on, and energization of the electric storage motor 1 is started.

[0006] When the mirror finishes operating and hits a stopper and locks, a lock current is detected and the internal relay 6 is turned off.

The seesaw switch 5 has three positions of forward rotation, reverse rotation, and OFF, and is configured to lock at a pressed position.

The door mirror is provided with a mirror heater for removing fine raindrops and fogging attached to the mirror surface.

The mirror heater is disposed on the back side of the mirror and raises the temperature by energization. A rear defogger is interposed between the heater main body 7 and the vehicle body side power supply 4. It is mainly constituted by a heater switch 8 which is energized to the heater main body 7 for a predetermined time by being also used as a switch.

It is to be noted that another example of this type is disclosed in Japanese Patent Application Laid-Open No. 6-247263.

[0011]

However, in such a conventional door mirror with a heater, as shown in FIG. 6, the expansion and storage of the door mirror and the energization of the heater body 7 are arranged in parallel. Since it is configured to be performed by a separate circuit, the heater switch 8 must be provided in a separate circuit independently of the electronic mirror control switch unit 3.

Therefore, the provision of the heater switch 8
The number of parts increases.

In addition, from the vehicle body side power supply 4 to the heater switch 8, or from the heater switch 8 to the heater body 7
Wiring and the like are required, and the total length of the wiring becomes longer.

It is necessary to carry out the power supply to the power supply substantially simultaneously.

However, even when it is desired to perform the opening of the door mirror and the energization of the heater main body 7 substantially at the same time, the driver separates the electric mirror control switch unit 3 and the heater switch 8 individually. It had to be operated and it was hard to say that the operability was good.

Further, if the deployment and storage of the door mirror and the energization of the heater main body 7 are performed at exactly the same time, the electrical load becomes large. There was also a problem that the capacity standard of No. 4 had to be set large.

The heater switch 8 is turned on to operate the rear defogger even when the door mirror is housed or when no fine raindrops or fogging is attached to the mirror surface. In this case, power is supplied not only to the rear defogger but also to the heater body 7. For this reason, there was a problem that power saving was difficult.

It was hard to say that the mounting workability was good, for example, that the harness wiring from the heater to the heater body 7 had to be separately arranged.

Moreover, in a vehicle having a door mirror of a normal electric storage type, since the heater switch 8 is not required, the appearance in which the heater switch 8 is provided is improved by fitting and processing. There is a problem that the number of manufacturing steps is increased, and this also causes an increase in manufacturing cost.
